Functionality is the heart of these guides, what you are really paying for. There are a lot of aspects I could look at with regards to functionality such as; questing path; quest progression; addon user interface; bugs; performance and many more.

All the other aspects aren’t worth comparing as both wow guides are light in terms of system usage, both have very few bugs, and both update your quest progress in real time.
Also note that power leveling is sometimes used to refer to paying someone else to level your character to cap as fast as possible (i.e. they power level for you); a distinction used by Blizzard is to refer to the paid leveling as "power leveling service."

Common methods of power leveling include doing only those quests which are most efficient in terms of experience over time, and analyzing the quests in a given zone so as to do them in the most efficient order possible.

Drustvar is far and away the hardest Alliance zone, which is exactly why you want to do it first. If you have legendary items, they’ll still be usable, and if you don’t, this zone will still be easier early on than it will be later. Drustvar is also extremely fast and will let you jump out ahead of your competition in other zones, which means fewer players around to take your quest objectives.
This Addon solves that issue where you have 5 Paladins in your Raid and no one can decide who is Buffing what. It has a little UI that represents Different Classes in your Party or Raid. You can change what buffs you want to give out then just mash the Class Button for each Class type until they all Turn Green. If anyone is missing a buff you are assigned the Class
If you're looking for simple, just get actionator. Set it to undercut everything you post for 1c and alt click from your bags. It will place the item on the ah window, do a scan for that item and autoset the price for how much you told to undercut (you can change it accordingly if you feel like it). It will remember if you do stacks for which items and replicate it everytime.
